两项研究测试的假设，在语音记忆中的儿童年龄小于2岁，可以使用非单词重复任务（NWR）进行评估，这些差异与儿童的词汇发展的速度。NWR准确性，真实的单词重复准确性和生产性词汇进行了评估，在15名儿童之间的1;9和2;0在研究1和21名儿童之间的1;8和2;0在研究2。在这两项研究中，NWR的准确性显着相关的词汇百分位数，而且，独特的占了很大一部分的词汇方差时，真实的单词重复准确性保持不变。研究结果确立了NWR作为非常年幼儿童语音记忆的有效测量方法，并为进一步研究语音记忆在早期单词学习中的作用打开了大门。
Two studies test the hypotheses that individual differences in phonological memory among children younger than two years can be assessed using a non-word repetition task (NWR) and that these differences are related to the children's rates of vocabulary development. NWR accuracy, real word repetition accuracy and productive vocabulary were assessed in 15 children between 1;9 and 2;0 in Study 1 and in 21 children between 1;8 and 2;0 in Study 2. In both studies, NWR accuracy was significantly related to vocabulary percentile and, furthermore, uniquely accounted for a substantial portion of the variance in vocabulary when real word repetition accuracy was held constant. The findings establish NWR as a valid measure of phonological memory in very young children, and they open the door for further studies of the role of phonological memory in early word learning.
